It is suited to hydroponics, aquaculture and environmental water monitoring where long-running measurements are needed.The pro probe is designed for 24/7 conductivity monitoring and includes an integrated PT1000 platinum resistance thermometer for temperature-compensated measurements. The signal is hardware filtered for low jitter, and the AC excitation source helps reduce polarisation effects to improve precision and extend probe life.It works from a 3.3–5V supply, making it compatible with both 3.3V and 5V controller boards such as Arduino. The kit is plug-and-play with no soldering required, and the supported library includes a calibration program. In the box you get an electrical conductivity probe x1, electrical conductivity signal conversion board (industrial grade) x1, PT1000 RTD signal conversion board x1, Gravity sensor cable x2, waterproof joint x1, waterproof aviation connector x1, electrical conductivity calibration standard solution 1413µs/cm x4, and nylon pillar screws kit x1.Features:Easier to measure the compensated temperature dataPlug-and-play, no solder requiredSpecifications:Supply Voltage: 3.3-5.0VOutput Signal: 0-3VProbe Type: Industrial GradeCell Constant: K=1Temperature Detector: PT1000 platinum resistance thermometerMaximum Range: 1-2200μs/cmPractical Range: 100-2000μs/cmOperating Temperature: 0-50℃ (non-freezing)Pressure Resistant: 0.5MPaWaterproof Level: IP68Cable Length: 5mA practical choice for building an Arduino-compatible electrical conductivity meter or a multi-parameter water quality tester using the DFRobot Gravity sensor ecosystem. **Product Type:** Water Quality Sensor ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDsEkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1b5035712fb845ee27dcafefc484621d9d84bce2/SEN0451_Main_01.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDsUkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--60787f0b92afc9b47e7b676ba192ca448039e508/SEN0451_ShipList_04.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDskkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--81caadb09a29b35165201f12273f60d62d37e39d/SEN0451_Detail_05.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDs0kBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--3626eb5ff60f010262727e06b31747fe0cc17856/SEN0451_Detail_06.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDtEkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--933ad44342b1990d9fdb74f0575a5300ca4de703/SEN0451_Detail_07.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDtUkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--909a7c6bb96e36b3442150e4279091792d830c0d/SEN0451-datail-001.jpg) - [Image 7](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDt0kBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--1b1ac02002089e0a2e46f5e951fe1aeb3f476300/SEN0451.jpg) - [Image 8](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDuUkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a516eb6ff081269f3c05b4dedf3faebf7674b1fa/SEN0451-detail-002.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
